The Save Method will perform an insert, update or delete of a single object or a list of objects.  Here is how it determines what to do:

• If there is an IsDeleted property and it is true, then the object will be deleted.
• Else If there is an IsNew property and it is true, OR if the primary key is the default value, then the object will be inserted.
• Else If there is an IsDirty property and it is true OR if there is no IsDirty property, then the object will be updated.
